For heavy solid wood frames or luxury leather upholstery, 500N to 600N struts are recommended. BLS provides free Newton calculation support.<\/p>\n<h4>Q2: How does the BLS-453 differ from full-size bed lift mechanisms?<\/h4>\n<p><strong>A:<\/strong> The BLS-453 has a significantly shorter bracket length (designed for ~1.2m to 1.5m chaise lids) and lower piston force (200N\u2013600N), making it compact and lightweight compared to 1.5m bed frames with 1000N+ struts.<\/p>\n<h4>Q3: What is the wholesale packaging specification for overseas sea freight?<\/h4>\n<p><strong>A:<\/strong> Packaged 1 pair per protective inner bag with piston hardware, 10 pairs per 5-ply reinforced export master carton, palletized on fumigated wooden pallets for container shipment.<\/p>\n<p>[Request a Free Quote and Technical Catalog]<\/p>\n<p>WhatsApp Inquiry:\u00a0<a href=\"https:\/\/wa.me\/message\/M6FPBFEHD773P1\" target=\"_blank\" rel=\"noopener\">Click to Chat: +8613827521875<\/a><\/p>\n<p>Email Support:<a href=\"ZK-ZhengKai@outlook.com\"> ZK-ZhengKai@outlook.com<\/a><\/p>\n<p>Discover More:\u00a0Explore our full Sofa &amp; Bed Mechanism Collection<\/p>\n<p><!-- \u4e13\u5c5e\u4e8e\u8d35\u5983\u69bb\u6c14\u538b\u67b6\u7684 Schema \u7ed3\u6784\u5316\u6570\u636e --><br \/>\n<script type=\"application\/ld+json\">\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@graph\": [\n    {\n      \"@type\": \"Product\",\n      \"name\": \"Heavy-Duty Gas Spring Storage Lift Mechanism BLS-453\",\n      \"description\": \"Compact hydraulic gas spring storage lift mechanism manufactured from 2.5mm Q235 steel by BLS Hardware.
